After less than three months, it's over for Canadian doubles legend Daniel Nestor and partner Rohan Bopanna

As  Daniel Nestor said during the Davis Cup in Vancouver last month, he's at a stage in his career at age 42 where he's just trying to keep up with the younger guys.

When it was good with new partner Rohan Bopanna, it was pretty good. But obviously it wasn't good enough, for long enough. After less than three months together, the pair will play with other partners when the clay-court season begins in a couple of weeks.

Nestor and Bopanna, who teamed up a couple of times – unsuccessfully – in 2014 before committing to 2015 as a pair after Nestor ended it with Nenad Zimonjic of Serbia, won a title in Sydney to start the season and another in Dubai last month.

On the surface, their 2015 record together looks pretty good: 12-5. But they haven't faced many of the very top teams, though they did defeat reigning French Open champs Julien Benneteau and Edouard Roger-Vasselin on their way to the Sydney title.

Along the way, they  lost to the pickup team of Kei Nishikori and Alexandr Dolgopolov (first round, Brisbane), Max Mirnyi and Feliciano Lopez (second round, Australian Open), Dominic Inglot and Florin Mergea (second round, Rotterdam), singles players David Ferrer and Fernando Verdasco (second round, Indian Wells). This week in Miami, the pair went out meekly to big-serving Sam Querrey and John Isner, who were playing just their third match of the 2015 season together.

That may have been the final straw, although Eh Game's sources report that both have been talking to other potential partners in the last few weeks.

We're told that Nestor will team up with another Indian player, the flashy showman Leander Paes, for the clay-court season.

And a blog in Romania (we can't vouch for its accuracy) reports that Bopanna has already committed to Mergea, a Romanian with whom he did well in 2014 in one event together. The blog reports that Mergea, whose new partnership with good pal Inglot wasn't working to his satisfaction, called Bopanna and suggested a short-term partnership for the tournament next week on clay in Casablanca, which Bopanna offered to extend longer term. The two played together at Shanghai last fall, and defeated both Canadian Vasek Pospisil and Jack Sock (11-9 in the match tiebreak, in a match that would have qualified the pair for the year-end championships) and the top team of Ivan Dodig and Marcelo Melo.

Meanwhile, Nestor had been feeling out Paes, the 41-year-old whose 55 career titles pale against Nestor's 87 – if that's even possible. Paes won the Australian Open mixed doubles with Martina Hingis this year, and had been playing with Raven Klaasen of South Africa in the injury absence of Radek Stepanek, a Czech veteran with whom he'd had good success.

Which came first? Ah; it seems everyone is handling all this musical-chairs business like grownups, so it's probably a moot point. These players have so much experience with so many different partners, they know pretty quickly what works and what doesn't.

The Paes-Klassen partnership began well, with a final in Chennai, a title in Auckland. They lost to the Bryan brothers at a smaller event in Delray Beach, and were soundly beaten by Nestor and Bopanna in Rotterdam. But Paes and Klassen also lost early in Miami, to Fabio Fognini and Simone Bolelli– their third loss to the Italian pair already this season. Perhaps that also was a catalyst for Paes to decide to commit to a change as well.

(Take a deep breath right here; got all that straight? We've hyperlinked to the players' biographies to help you wade through the drama).

These are hardly poor results; there are plenty of teams out there who would gladly take them. But the standards are high for players like Nestor and Paes, with their illustrious resumés.

Paes is another familiar partner; he and Nestor teamed up for several events at the end of the 2013 season, when Nestor's partnership with the mercurial Robert Lindstedt didn't work out. They won the ATP Tour event in Winston-Salem just before the U.S. Open – Nestor's only ATP Tour title in a down year.

Another thing they did together was defeat Isner and Querrey easily – 6-2, 6-2 – in Shanghai that fall.

Seriously, the specialists are like a bad episode of Knot's Landing; so much drama and swapping around the doubles cul-de-sac.

But Nestor doubles matches will instantly become popcorn affairs. Paes is flashy, a gifted shotmaker, and a total ham on the court. He's as entertaining as they come. And if he'll let Hingis play the ad side, as he did in Australia, he'll certainly have no problem letting Nestor do the same.

Nestor and Paes are the first men's doubles team to officially enter Madrid and the French Open. So obviously they're excited to get started on their new adventure. They're also playing Barcelona.
